Snap your plate. See what it means for your PCOS.
A food and symptom journal that reads labels correctly, shows patterns in your energy, cravings and cycle, and has a real free plan. Weight tracking is optional and off by default.
What you get
Snap, scan or type
Scan a barcode or a nutrition label and you get the label's own numbers. Snap a plate and you get an editable estimate of carbs, sugar, added sugar, fiber and protein.
Symptoms first
Check in on energy, cravings, mood, skin, bloating and sleep in about 5 seconds, then see which meals line up with how you feel. Log periods too, with no predictions pushed at you.
Spot your patterns
After a week or so of logs and check-ins, Cyster Plate compares your higher and lower days and shows what you might notice. Your logs only, not a medical finding.
A summary for your doctor
Make a clean one-to-four-week summary of your logs and check-ins to bring to an appointment.
Recipes and plans
Quick everyday recipes adapted from US government nutrition programs, with credit shown, plus simple weekly plans and a grocery list.

Questions
Is it free?
Yes. The free plan includes AI photo or text estimates (4 a week), unlimited barcode, label, search and manual logging, unlimited symptom check-ins, your top weekly pattern, the last 4 weeks of Progress and one full doctor summary. Plus adds AI logging for every meal, all patterns, full history, unlimited doctor summaries and meal plans.
Is this a weight-loss app?
No. Weight is optional and off by default. The focus is how food relates to how you feel.
Is this medical advice?
No. Cyster Plate is a journal and educational tool. Talk to your doctor about anything medical.
How accurate is the photo logging?
A photo gives an estimate, shown as an estimate, with a confidence level for each item, and every number can be edited before you save. Barcodes and labels use the label's numbers. We publish how we test on the sources and method page.
Where does my data go?
Your logs, check-ins, periods, water and weight stay on your iPhone. If you allow AI estimates, the photo or text you submit goes through our server to Google to make the estimate, and we do not store it. Details are in the privacy policy.
iPhone only?
iPhone first. Other platforms may follow if there is demand.
